Treat Keychron C3 Pro as Keyboards & Mice. Confirm the item in the photos is that type, then compare a checkable spec. Skip listings that only repeat the search words with no size, count, or format.
If the contents will not match the query after that check, leave the listing and try the next card.
Write down the model or size you need for Keychron C3 Pro. Availability and price still belong on the product page.
